President Donald Trump’s legal team has already moved to trademark the slogan “Keep America Great!” — a phrase he recently said would be part of his 2020 re-election campaign.

The trademark application was filed with the U.S. Patent and Trademark Office on Jan. 18 — two days before Mr. Trump was officially sworn in as president.

The application indicates the phrase could be used for T-shirts, tank tops, “baby clothing, namely, one piece garments,” and “printed publications, namely, pamphlets providing information regarding Donald J. Trump as a political candidate.”

He recently told The Washington Post that his re-election slogan would be “‘Keep America Great,’ exclamation point,” and reportedly asked a lawyer to trademark and register the phrase with and without an exclamation point.

Mr. Trump moved to trademark “Make America Great Again” soon after the 2012 election.

“I can’t believe I got the copyright on that one, but I guess I have a good lawyer, right? That’s what I do,” he said on MSNBC in August 2015.
